Definitions

  • the drive unit of motor vehicles (the engine and the associated transmission) is increasingly subjected to regulation and control mechanisms in order to optimize the interaction of the engine with the transmission; for example, in order to reduce the fuel consumption of motor vehicles in addition to improved control of the engine, the gear ratio must also be adapted.
  • CVT transmissions '' Continuous Variable Transmission
  • the transmission element (chain, belt, belt etc.) arranged in the pulley sets can continuously (continuously) change the required gear ratio: by applying the same value of the contact pressure to the two pulley sets - this corresponds to the so-called preload force - the force level for the transmission element is set ; by specifying different values of the contact pressure on the two sets of disks, an additional force component is generated for transporting the transmission element, the gear ratio being infinitely variable in any steps by varying the contact pressure and thus the transport force can be varied.
  • the control methods used in continuously variable transmissions usually use a transmission controller or speed controller as the controller.
  • the transmission input speed or drive speed is regulated, which results as a product of the transmission output speed or output speed (disturbance variable) proportional to the vehicle speed and the transmission ratio (manipulated variable).
  • the control circuit has a summation element at the controller input to which the setpoint of the transmission input speed is supplied as the reference variable as the first summand and the actual value of the transmission input speed as the control variable as the second summand;
  • the control deviation obtained by forming the difference between the two setpoints of the gearbox input speed and the actual value of the gearbox input speed at the output of the summation element is fed to a control element consisting of a proportional controller, limiter and low-pass filter, at whose output (the controller output) the time derivative (the gradient) of the gearbox input speed is applied.
  • a second control circuit in the form of an acceleration controller can be subordinated to the speed controller, in which the time derivative (the gradient) of the gearbox input speed provided by the controller output of the speed controller forms the reference variable; ie in addition to speed control, speed gradient control takes place.
  • a disadvantage of these methods for controlling continuously variable transmissions is that the control element of the speed controller, which generates the setpoint of the gradient of the transmission input speed based on the control deviation (the speed difference of the transmission input speeds) and thus determines the control behavior, has a constant proportional component, i.e. the adjustment speed or adjustment rate of the transmission input speed and so that the control behavior is always the same (regardless of the respective setpoint specification for the transmission input speed).
  • the invention has for its object to provide a method according to the preamble of claim 1, in which a monitoring or control of the control behavior is made possible in a simple manner.
  • the control element of the speed regulator is implemented by means of a non-linear filter element in the case of a two-stage regulator comprising a speed regulator and a subordinate (downstream) speed gradient regulator;
  • the control curve and thus the gradient (the adjustment speed) of the setpoint of the gearbox input speed can be variably specified as the output variable of the speed controller by the influence of the control on the gradient of the target value of the transmission input speed (ie to the target value specification for the subordinate speed gradient controller) is varied as a function of the operating conditions of the motor vehicle.
  • the respective course of the filter function (range limits, limit values, maximum values, minimum values, gradients, etc.), ie the functional dependency of the output variable gradient (adjustment speed) of the setpoint of the transmission input speed on the input quantity setpoint of the transmission input speed and thus the respective control process can be - for example using a ( two-dimensional) characteristic curve or a (three-dimensional) characteristic diagram - are specified or varied in accordance with different operating conditions of the motor vehicle; for example depending on the respective driving situation (overtaking maneuvers, kick-down "of the accelerator pedal, braking processes), and / or the current vehicle speed, and / or the current transmission ratio and / or the maximum possible mechanical change speed for the transmission ratio, and / or the environmental conditions (for example slip detection, train operation / push operation, trailer travel, Uphill) and / or the driver type (engine power requirement of the respective driver) and / or the size of the control deviation (speed difference from the actual value and setpoint of the transmission input speed) etc.
  • characteristic function curve for example characteristic curve or characteristic curve curve
  • the appropriate filter function is generated as the current filter function using the defined filter functions; on the basis of the current filter function with its characteristic function curve (characteristic curve or characteristic curve curve) and its function values, the filter values result as the output variable of the speed controller, with which the speed gradient controller is acted upon as a reference variable.
  • two or more filter functions can be used to determine the filter values (the function values of the current filter function); For example, an interpolation between the function values of two or more filter functions can be carried out, and the function value averaged in this way can be supplied to the speed gradient controller as a filter value.
  • the filter functions ie the specification of the function values of the filter functions
  • the system limits of the controller, empirical customer requests and the driving characteristics of the motor vehicle must be taken into account.
  • the control behavior of the two-stage controller consisting of the speed controller and subordinate speed gradient controller can be adapted to different circumstances or requirements and thereby the driving comfort, driving behavior and consequently, driving safety can also be improved.
  • FIG. 1 showing a block diagram of the regulator with the two control circuits speed regulator and speed gradient regulator
  • FIG. 2 and FIG. 3 the course of two filter functions of the filter element of the speed controller for two different, show criteria characterizing the operating conditions of the motor vehicle.
  • the two-stage regulator of the first control circuit 1 for controlling the transmission input speed n IN as product n OUT ⁇ ÜV the transmission output speed N OUT (this is proportional to the speed of the motor vehicle), and the gear ratio UV and from the first Second control loop (downstream) of control loop 1 (speed gradient controller) for controlling the gradient (the time derivative d / dt) of the transmission input speed n IN .
  • the first control circuit 1 has a summation element 11 at the controller input RE1, to which the setpoint n IN, TARGET of the transmission input speed n IN as the command variable FG1 and as the second summand the actual value n IN, ACTUAL the transmission input speed n IN as the control variable RG1 are supplied.
  • the second control circuit 2 has at the controller input RE2 a summation element 21 connected to the controller output RA1 of the first control circuit 1, to which the setpoint d / dt (n IN, TARGET ) of the gradient d / dt (n IN ) is the first addend from the first control circuit 1.
  • the transmission input speed n IN as a reference variable FG2 and as a second summand the actual value d / dt (n IN, IST ) of the gradient d / dt (n IN ) of the transmission input speed n IN is supplied as a control variable RG2.
  • the multiplier 24 connected to the output of the actuator 23 is supplied with the manipulated variable SG gear ratio UV as the first product factor and the gear output speed n OUT acting as the disturbance variable StG as the second product factor; the actual value is obtained by multiplying the two variables gear ratio UV and gear output speed n OUT n IN, gearbox input speed n IN is formed.
  • the actual value n IN, IST of the transmission input speed n IN at the output RA2 of the second control circuit 2 is used as the control variable RG1, the summation element 11 at the controller input RE1 of the first control circuit 1 and - via a differentiator 25 to form the time derivative - as the control variable RG2 the summation element 21 am Controller input RE2 of the second control circuit 2 supplied.
  • the filter function FF is designed e.g. B. for comfort, maximum vehicle acceleration or optimal consumption.
  • the filter function FF provided to the filter element 12 generates the appropriate current filter function FFa (either using the function values of only one of the filter functions FF or using the function values of at least two filter functions FF);
  • the function values of the current filter function FFa are supplied as filter values FW to the summation element 21 at the controller input RE2 of the second control circuit 2 as a reference variable FG2.
  • the control behavior of the second control circuit 2 is influenced by a suitable choice of the course of the filter functions FF of the filter element 12 or by a suitable generation of the respective current filter function FFa or the filter values FW in such a way that when the setpoint value n IN, TARGET the transmission input speed n IN the gear ratio UV is changed as manipulated variable SG according to the current request (for example, consumption-optimized).
  • the qualitative course for filter functions dependent on the driver type is shown using the example of two filter functions FF1 and FF2, the course of filter function FF1 for one sporty "driver with a high power requirement and the course of the filter function FF2 for one economic "driver with a low power requirement is characteristic.
  • each driver of the motor vehicle can now be assigned either one of these filter functions FF1, FF2 as the current filter function FFa or, depending on the driving behavior of the driver, the current filter function FFa by suitable ones Interpolation between these two filter functions FF1, FF2 can be obtained.
  • the quantitative curve for filter functions dependent on the driving state of the motor vehicle is shown using the example of two filter functions FF3 and FF4, the course of filter function FF3 for overrun mode (the motor vehicle is not driven by the engine) and the curve the filter function FF4 is characteristic of the train operation (the motor vehicle is driven by the engine); an overrun operation is assumed here with an accelerator pedal angle or throttle valve angle of less than 1 °, a pull operation on the other hand with an accelerator pedal angle or throttle valve angle of more than 1 °.
  • the course of the filter function FF (in particular its slope and limit values) can be adapted or varied accordingly for other operating conditions of the motor vehicle or other boundary conditions (for example kick-down, idling, operated brake).
  • the current filter function FFa which is most suitable (adequate) for two or more criteria used for the operating conditions of the motor vehicle can be determined either by specifying an already defined filter function FF or by suitable interpolation between at least two already defined filter functions FF.
